DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0024] I. The Invention

[0025] The invention and the various features and advantageous detailsthereof are explained more fully with reference to the nonlimitingembodiments that are illustrated in the accompanying drawings anddetailed in the following description of preferred embodiments.Descriptions of well known components and processing techniques areomitted so as not to unnecessarily obscure the invention in detail.

[0026] Referring to FIG. 8, a chassis is depicted comprising two modulebay sections, including two module bay forward sections 30 and twomodule bay rearward sections 31.

[0027] There can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,17, 18, 19, 20, 25, 30, 40, or more forward and rearward module baysections in the chassis. The forward and rearward sections comprise thearea between the front of the chassis and the intersection board 34 andthe area between the intersection board 34 and the rear of the chassis.The chassis comprises an intersection board 34 between the forward andrearward module bay sections. If the intersection board 34 is placedsubstantially symmetrically between the forward 30 and rearward 31module bay sections, it is also referred to as a midplane board. Theintersection board 34 may be located in any plane in the interior of thechassis between the front 40 and the rear 41 of the chassis. Theintersection board 34 may be located about 10%, about 20%, about 25%,about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about80%, or about 90% of the way from the front of the chassis 40 to therear of the chassis 41. The intersection board 34 is shown extending theentire width of the chassis. The intersection board 34 in FIG. 8 willextend at least a portion of the interior width of the chassis; it mayextend the width of less than about 10%, about 20%, about 30%, about40%, about 50%, about 60%, about 70%, about 80%, about 90%, or about100% of the interior chassis width. The height of the intersection board34 shown in FIG. 8 is less than the interior height of the chassis. Theheight may be about 0.1, about 0.2, about 0.3, about 0.4, about 0.5,about 0.6, about 0.7, about 0.8, or about 0.9 times the interior heightof the chassis.

[0028] There is no difference between the forward and rearward sectionsof the chassis as demonstrated in FIG. 8. The terms “front” or “forward”and “rear”, “back”, or “rearward” when referring to the chassis are notrelated to the orientation of the chassis in a room or to theorientation relative to the force of gravity. These terms are usedsolely for the convenience of demarcation and communicating relativepositions within the chassis. If a chassis of the current invention isrotated 180° and the “front” and “rear” are relabeled, there would be nofunctional difference between the chassis before rotation and thechassis after rotation.

[0029] Still referring to FIG. 8, the intersection board 34 can be avirtual intersection board. A virtual plane is created when a pluralityof modules are coupled to each other. Modules at least in-part withinthe forward and the rearward sections of a modular bay or at leastin-part within adjacent modular bays may be connected to each otherinstead of an intersection board. These electronic connectors create avirtual plane within the chassis which extends in a directionsubstantially parallel to the front and rear faces of the chassis. It iscontemplated that the virtual intersection board 34 span a portion ofthe interior width of the chassis. For example, a module located atleast in-part within a forward section of a module bay can beelectronically coupled at a point located substantially symmetricallybetween the front of the chassis and the back of the chassis to a modulelocated at least in-part within the rearward bay section of the chassis.Modules in adjoining module bay sections may or may not also beelectronically coupled to each other or to the modules previouslydescribed. To couple modules in adjoining bay sections, it would berequired to have a connector on the modules facing substantiallyorthogonal to the direction of insertion for the module such that theconnector would contact a similar connector when a module was insertedinto an adjacent modular bay. The height, width, and location within thechassis of the virtual intersection board 34 may be varied similarly tothat of an intersection board. The virtual intersection board 34 may belocated about 10%, about 20%, about 25%, about 30%, about 40%, about50%, about 60%, about 70%, about 75%, about 80%, or about 90% of the wayfrom the front of the chassis to the rear of the chassis. The virtualintersection board 34 will extend at least a portion of the interiorwidth of the chassis; it may extend the width of less than about 10%,about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about80%, about 90%, or about 100% of the interior chassis width. The heightof the virtual intersection board 34 is less than the interior height ofthe chassis. The height may be about 0.1, about 0.2, about 0.3, about0.4, about 0.5, about 0.6, about 0.7, about 0.8, or about 0.9 times theinterior height of the chassis.

[0030] An additional board, an intermediate board, may be coupled to thechassis. The intermediate board is located either between theintersection board 34 and the front of the chassis or between theintersection board 34 and the rear of the chassis. For example, anintersection board may be located substantially symmetrically between afront of the chassis and a back of the chassis. An intermediate boardmay be located substantially symmetrically between an intermediate boardand a back of the chassis. The intermediate board may also be a virtualintermediate board. For example, the intermediate board may be solidstate while the intersection board is be virtual or both theintermediate board and the intersection board are virtual. More than oneintermediate board may be located within a chassis.

[0031] Referring to FIG. 9A, a chassis is shown with a module 50positioned to be inserted into both a forward 30 and a rearward 31modular bay section. The module 50 positioned to be inserted into therearward modular bay section 31 is shown as a solid component and themodule 50 positioned to be inserted into the forward modular bay sectionis shown by dotted lines. The module 50 comprises two different heightssuch that the height of the end of the module inserted into the modulebay first is less than the height of the end of the module that willcontact the chassis last. Connectors 51, represented by the diamond andsquare in the upper part of the module, can connect to the intersectionboard or an intermediate board within the chassis. The connectors 51 canalso connect to another module to create a virtual intersection board.It is contemplated that the connectors on the module could be positionedat various positions between the two ends of the module. For example,the connector could be halfway between ends of the module as shown inFIG. 9A. The connectors could be located about 10%, about 20%, about30%, about 40%, about 50%, about 60%, about 70%, about 80%, or about 90%of the way from end of the module that is inserted into the module bay.

[0032] Although FIG. 9A is drawn such that any intersection board mustbe located in the upper half of the chassis to connect to the module 50,it is understood that the designations of top and bottom can easily bereversed. A chassis of the current invention with an intersection boardlocated at the bottom of the chassis would require the module 50 shownin FIG. 9A to be vertically flipped 180° before insertion into thechassis.

[0033] Referring to FIG. 9B, the chassis and module 50 of FIG. 9A isshown after insertion of the module 50. The orientation of the insertedmodule 50 is depicted in FIG. 9A as having solid lines. A repositionableplate 20 is shown in an orientation for connection through one or moreconnectors 52 with the chassis and module 50. The repositionable plate20 is configured such that it can be connected to the chassis via platemounting brackets located on the module bays of the chassis. If a module50 is inserted into the front of the chassis, the repositionable platewould then be connected to the chassis and module 50 from the back ofthe chassis. The repositionable plate comprises a plurality of elements53 which can include manually actuatable fasteners such as thumb screws,ventilation slots and electrical feedthroughs which are capable ofconducting power or communicating data.

[0034] A repositionable plate is modular in nature. Repositionableplates can interchangeably be connected to the module bays of thechassis. A repositional plate may be sized to connect to 1, 2, 3, 4, 5or more module bays. It can be seen from FIGS. 2A-2C and 4A-4C that therepositionable plate of FIGS. 4A-4C is twice the width of therepositionable plate of FIGS. 2A-2C. Similarly, the module of FIGS.3A-3C is twice the width of the module of FIGS. 1A-1C. It is an aspectof the current invention that one module and/or one repositionable plateis connected to a plurality of modular bays.

[0035] It is not necessary that a repositionable plate connected to achassis be connected to a module located in the modular bay directlybehind the repositionable plate. The repositionable plate may beconnected to a module located in any of the module bays in the chassisby means of wires, cables, or other connectors in the interior of thechassis. This allows for the placement of connections external to thechassis into more preferred positions without creating a “rats nest” ofwires.

[0036] The particular material used for the repositionable plates shouldbe strong and durable. Conveniently, the repositionable plates of theinvention can be made of any metal material. If a conductive material isused, it is preferred that the material be coated with an insulatinglayer such as, for example, paint. For the manufacturing operation, itis an advantage to employ a cold rolled sheet steel material.

[0037] However, the particular material selected for the repositionableplates is not essential to the invention, as long as it provides thedescribed function. Normally, those who make or use the invention willselect the best commercially available material based upon the economicsof cost and availability, the expected application requirements of thefinal product, and the demands of the overall manufacturing process.

[0038] The particular manufacturing process used for fabricating therepositionable plates should be inexpensive and reproducible.Conveniently, the manufacture of the repositionable plates of theinvention can be carried out by using any sheet metal fabricationmethod. If sheet metal is used, it is preferred that the processingstart with perforating, followed by forming, and then optional paintingand attachment of hardware (e.g., feed-throughs, thumbscrews,etceteras).

[0039] However, the particular manufacturing process used for making therepositionable plates is not essential to the invention as long as itprovides the described functionality. Normally those who make or use theinvention will select the manufacturing process based upon tooling andenergy requirements, the expected application requirements of the finalproduct, and the demands of the overall manufacturing process.

[0040] The invention can also be included in a kit. The kit can includesome, or all, of the components that compose the invention. Morespecifically, the kit can include a chassis, the module bay sections andother components of the invention. The kit can also include anintersection board or an intermediate board. The kit can also containinstructions for practicing the invention and apparatus for carrying outthe invention. Unless otherwise specified, the components (and apparatusand/or instructions) of the kit can be the same as those used in theinvention.

[0041] The term substantially, as used herein, is defined as at leastapproaching a given state (e.g., preferably within 10% of, morepreferably within 1% of, and most preferably within 0.1% of). The termcoupled, as used herein, is defined as connected, although notnecessarily directly, and not necessarily mechanically. The termdeploying, as used herein, is defined as designing, building, shipping,installing and/or operating. As used in the specification, “a” or “an”mean one or more. As used in the claim(s), when used in conjunction withthe word “comprising”, the words “a” or “an” mean one or more than one.As used herein “another” may mean at least a second or more.
